Fig. 1 Sectional view of the weapon 



Both the barrel and slide are engaged by rollers and locked together as an assembly. 
Recoil move the slide assembly to the rear, compressing the recoil spring. The roller cam, 
which retains the rollers in locked position, rests against a similarly configured frame lug. 
After overcomming short recoil (6 mm), the rollers are disengaged and the barrel lug abuts 
the frame as the slide continues reawards. The case is extracted and is ejected through the 
port by the frame mounted ejector. 

Trigger mechanism is of the single-action type. The firing pin is equipped with an 
automatic safety catch preventing firing until the trigger has been pulled. This prevents an 
accidental discharge of the weapon, even with an unintentional impact onto the hammer. 

The frame-mounted safety has three positions. The lower is the "fire" mode and exposes 
a red detent. In the middle position, the safety engages both, the trigger bar and the rebound 
notch of the hammer. This allows the weapon to be "cocked and locked" or safety unloaded. 
The upper position, provides a decocking function that causes the hammer to fall as the 
safety rotates into the rebound notch of the hammer. 

Pistol stripping and assembling is very simple, cleaning and maintenance require only 
minimum time and work. 

The pistol has been completely overhauled. After simple barrel exchange is given the 
possibility to fire the weapon in corresponding calibre. 



STRIPPING & ASSEMBLING 

The weapon can be stripped down into folowing assemblies, Fig. 2:

Fig. 2 The weapon stripped 




TO STRIP: 

1 . Remove the magazine by pressing the magazine catch. Retract the slide, checking the 
chambre to insure that the pistol is unloaded. Allow the slide to return to battery and elevate 
the safety to its uppermost position causing the hammer to fall against the hammer block. 

2. Pull down the serrated tabs of the takedown latch located on both sides of the frame in 
front of the trigger guard, Fig. 3a. This releases the slide assembly to move 6 mm forward 
and lift straight up off the frame. 

3. Invert the slide assembly and insert a magazine bottom plate extension in the slot in the 
roller cam, Fig. 3b. Retain the slide with one hand while moving the roller cam forward to 
disengage the rollers from the slide recesses. With the bottom plate extension canted 
slightly to the rear, tilt the breech of the barrel assembly out about 1 0° and withdraw it to the 
rear. Take recoil spring off the barrel.

TO ASSEMBLE: 

1. Place the recoil spring on the barrel assembly than place the front end of the recoil 
spring in the muzzle of the slide. Insert a magazine bottom plate extension in the slot in the 
roller cam to move the muzzle of the barrel forward through the front of the slide. Lower the 
breech of the barrel assembly into the slide allowig it to retract into position. 

2. Place the slide assembly on the frame in the 6 mm forward position, aligning the lugs 
and assembly slots. Apply downward pressure and move the slide to the rear until the 
takedown latch snaps into place to engage and retain the slide. 

3. Install the magazine to complete reassembly. 



CLEANING AND MAINTENANCE

weapon immediately after shooting and to apply a thin protective layer of a good quality 
gun oil. Wipe dry the barrel bore befor firing. Keep the surface of the weapon clean and dry.

failures of the weapon.

your shot is going to strike. 

- Whenever you handle a gun, or hand it to someone, always open the action immediately 
and visualy check the chamber, receiver and magazine to be certain they do not contain 
any ammunition. 

- The sequence of stripping the weapon is important to prevent damage to the working 
parts. It will not be stripped further than taught.
